Is your motor a servomotor with an integrated encoder feedback built into it ? Or are you using a more ordinary induction motor ?
Current motors are SEW gearmotors
Is there an encoder built into or attached close to the motor shaft itself, or is the linear encoder on the mechanism your only form of position feedback ?
The gearmotors are fitted with an encoder placed close to the shaft, however, the carriage that it travels on is on a belt and pulley, we attempted to run it with only this encoder but the cuts were far outside of our desired tolerance ranges. The linear encoder appears to be the most accurate.
Is your AMO linear encoder an incremental or absolute device ? What kind of signal does it put out ?
It is an incremental TTL encoder device. The old tape became damaged and we had to replace it, issue was that our storeroom didn't stock the correct part and got an encoder tape without zero points. This led us to try and adapt the SEW code to refence off of our overtravel cam, however, we were unable to do so and could not reach proper support from the manufacturer.
Are you using a ControlLogix, or a CompactLogix with an "M" in its part number ?
Current plan was to buy a 1769-L27ERM-QBFC1B as this would have the sufficient amount of I/O and the ethernet capabilities to communicate with the drive and HMI.
The old system just took the linear encoder feedback and sent it to the SEW drives which then instructed the gearmotors to arrive at a certain point. Issue is the programming is in French and I had great difficulty translating and understanding it English. Hope this helps.
